Overtemperature Fuses from China Suppliers - OT-F & OT-S Types for Electrical Equipment Protection from Factory
When fuse body and its ambience temperature rises to the melting point of the organic compound, the compound changes from solid state to liquid state. Under the action of spring elasticity, the contact is pushed off to cut off the current.
- Product of organic compound type
- Temperature band is rich (73–240°C)
- Accurate action temperature
- Not recoverable
When fuse body and its ambience temperature rises to the melting point of Thermal fuse, the alloy is spherical fused under the surface tension of flux, cutting off the circuit and playing a protective role.
- Environmentally fusible alloy type
- Plastic case
- Accurate action temperature
- Not recoverable
Temperature rise: Heat is transferred to bimetallic strip to reach the operating temperature value, and the contacts are disconnected. Temperature drop: Bimetallic strip quickly restored to original state, contact closed and circuit connected.
- Small size, easy for installing
- PBT case, metal case, epoxy seal
- Auto reset bimetallic strip, usage count more than 10,000 times
- Moistureproof, dustproof, anti soaking paint
- Superior thermal response, double protection for current & temperature
- Customized based on customers' requirements
When the temperature of the protected electrical apparatus rises, the heat generated is transferred to the bimetal sheet element, and when the predetermined operating temperature is reached, the bimetal sheet element acts quickly, pushing the moving contact to disconnect the contact, thereby cutting off the circuit; when the temperature drops to the rated reset temperature, the bimetal sheet element automatically restores the circuit to be connected.
- Max operation current 16A
- 100,000 times long life
- Quick action
- Superior thermal response
- Ceramic high temperature resistant bracket
